We divide 86450542 by 839
Our goal is to divide 86450542 by 839.

Going ahead to step 1:
839 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 839

Step 2:
839 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 839

Going ahead to step 3:
839 can be fit into 864 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 839 away from 864, we end up with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 839

Step 4:
If we divide 255 by 839, we get 0 and a remainder of 255.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 255, we end up with 255.
Append the next digit (0) from the dividend to 255 and continue with: 2550 / 839

Step 5:
2550 divided by 839 is 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 103.0
Subtract 2517 from 2550 to get 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 839

On to step 6:
When dividing 335 by 839, we get 0 with a remainder of 335.
The number 0 becomes the next digit in our result. 
Result so far: 1030.0
If we subtract 0 from 335, we get 335.
Include the next digit (4) from the dividend after 335, then repeat: 3354 / 839

On to step 7:
If we divide 3354 by 839, we get 3 and a remainder of 837.
Put 3 as the next digit of the answer. 
Result so far: 10303.0
If we take 2517 away from 3354, we end up with 837.
Bring next digit (2) of the dividend behind the 837 and repeat the process: 8372 / 839

On to step 8:
When dividing 8372 by 839, we get 9 with a remainder of 821.
The next digit of our result is 9. 
Result so far: 103039.0
The remainder is 821 after subtracting 7551 from 8372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

On to step 9:
839 can be fit into 8210 9 times, resulting in a remainder of 659.
The next digit of our result is 9. 
Result so far: 103039.9
If we take 7551 away from 8210, we end up with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

On to step 10:
839 can be fit into 6590 7 times, resulting in a remainder of 717.
Put 7 as the next digit of the answer. 
Result so far: 103039.97
The remainder is 717 after subtracting 5873 from 6590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Step 11:
The number 839 fits into 7170 8 times, leaving a remainder of 458.
The number 8 becomes the next digit in our result. 
Result so far: 103039.978
The remainder is 458 after subtracting 6712 from 7170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Step 12:
839 goes into 4580 5 times with a remainder of 385.
Put 5 as the next digit of the answer. 
Result so far: 103039.9785
Subtracting 4195 from 4580 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 13:
839 goes into 3850 4 times with a remainder of 494.
The next digit of our result is 4. 
Result so far: 103039.97854
If we take 3356 away from 3850, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 14:
When dividing 4940 by 839, we get 5 with a remainder of 745.
Use 5 as the next digit of our solution. 
Result so far: 103039.978545
Deduct 4195 from 4940 and we're left with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Step 15:
When dividing 7450 by 839, we get 8 with a remainder of 738.
Use 8 as the next digit of our solution. 
Result so far: 103039.9785458
Subtracting 6712 from 7450 leaves us with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Advancing to step 16:
The number 839 fits into 7380 8 times, leaving a remainder of 668.
The number 8 becomes the next digit in our result. 
Result so far: 103039.97854588
Subtract 6712 from 7380 to get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

The quotient of the division is 103039.97854588, and the remainder is 6.68e-07.
